Generally, the solution to 'my character died' shouldn't be 'how can I smash this campaign?', but if you insist, there are a great many ways to smash a campaign. Wizard, Cleric, Druid, Wizard again, StP Erudite.. hell, the tier 2 classes can smash campaigns, too, if they try.
So the question becomes, how do you want to smash the campaign?
